There is a species of shark called the whale shark which has the same feeding method as the large baleen whales; it filters food out of the water. It is also the largest species of shark.
you are more likely to get killed by a coconut then a shark most shark attacks are non fatal
Thresher sharks avoid humans. There is only one known case in the history of record keeping where a thresher shark bit a human. It was provoked by the human (probably fishing), and was a non-fatal incident.
Probably the least dangerous shark is the biggest one - the whale shark. Sluggish plankton and krill eaters of tropical seas, their teeth are very small, and most ichthyologists believe they are probably useless. They are non-aggressive.
Probably the whale shark, Rhincodon typus, which can grow to over 20 tons.
Bala sharks are non-aggressive. I have had several of them, and they have never tried to attack or harm the other fish in the tank.
